Specification of Letters Patent. Patented Jano 3, 19220 Application `filed March 22, 1919. Serial No. 284,411.

To all whom it may concern:

Be it known that I, ABRAHAM Nevron, a citizen of the United States, anda resident of New York, borough of Manhattan, in the county of New York and State of New York, have invented-certain new and usefull Improvements in Processes and Mechanisms for Attaching Strings to Envelopesand the like, of which the fo lowing is a specification.

This invention relates to processes and mechanisms for attaching string to envelopes and the like, and is particularly directed to means for attaching to the bodies or flaps,

or both, of envelopes, one. or more washers, as by means of eyelets, and thereafter afxing a string to the body or flap portion of the envelope by winding that string'between a washer and the en-velope body or lian.

The object of my improvements is toI provide means to these ends ofgreater eliiclency and higher speed than is 'possessed by any mechanism known to me, and particularlyl to provide novel means for applying thev string by a novel method. I

With these. ends in view my improvements comprise features illustrated inthe drawings accompanying this specicatlon and showing the present preferred embodlment of my improvements, wherein5- Figure 1 is a front elevation, partly 1n section on line 1-1 of Fig. 2, ofso much cfaV washer and string attaching machine as suilices to show myv improveemnts. .Fig 2V .tiorn showing the winding of the string.

Figs. 8 and 9 are a bottom lan 'view and sectional elevation, respectlve y, showing alternate means adapted to receive thestringwinding. Figs. 1 to 6, incluslve, are to one scale, and Figs. 7 to 9, inclusive, are tofan" other and larger scale.

My improved mechanism includes a pair Vwasher supply devices and an eyelet supply device.- As illustrative of`one form of eyelet supply device and of washer supply device which are adapted for usewith my *im-v provements, I have shown the mechanisms employed for those purposes set forth in my Letters Patent of the United States No. 1,104,128, dated July 24, 1914, and for my present use Lhave shown two of such washer supply devlces. This device is illustrated as particularly adapted for supplying round washers which havebeen .previously formed and provided with a central hole there- -through and which are delivered from the bottom of a hopper by means of a reciprocating slide. It will be obvious, however, to those skilled in the art that other shapes of washer are equally applicable and that other washer supplying devicesmay be equally ef- `ficient.. For instance the device` of Olm, set

forth in Letters Patent of the United States i No. 1,114,177, dated October 20, 1914, in which square or rectangular washers are cut from the leading end of an endless paper or fabric tape, would be equally ecient.

Referring now to the drawings more in detail, 2 is the upper plunger carrying on its lower end eyelet' setting die 4 and, surrounding that die, presser-ring '5. Said plunger may be reciprocated at suitable predetermined times by means not shown, con

nected `with eye 6 .at theupper end of said plunger.` Said plunger is sugported forendwise movement bearing iixed to some permanent framing not shown.

Lower plunger 8 is mountedior rotation-in sleeve 9 but is restrained against endwise, movement relatively thereto by collar 10 thereon,X which engages thef upper end of said sleeve, and b pinion 12 and nut 11, the latter threade onto the lower end of said plunger, the pinion engaging the lower end of said sleeve. At suitable predetermined times plunger 8 is"rotated and to this end outstanding from sleeve 9. Shaft 18 is os cillated at predetermined times, by means not shown but which may be of known character, to cause plunger 8 at one time to rise to the position of Fig. 4 and at another time to descend to the position of Fig. 5. The

length of pinion 12 is suliicient to permit of said rising and descending while continuing in mesh with gear 13. Below gear 13 is constantl rotating' ear 80, and gear 13 is frictional y driven t erefrom, one revolution at a time, said gear 13 being liberated for rotation by the withdrawal of latch 66 from engagement with lug 67 on said gear. Gear 13 is normally at rest, but when rotated at predetermined times by the clutch mechamsm, is `caused. to makev one complete rotation-and stop. Said gear, being twice the diameter of pinion 12 meshing therewith,

will therefore cause said pinion to make two complete rotations and stop.

1 Reverting now to plunger 8, which is preferably of tubular construction, within the upper4 ortion of the bore thereof is slidably carrie needle 21, and spring 22 is eiiicient for urgin said needle upwardly in said plunger. he upper end of said plunger may be provided with seat 23 for the eyelet and with annular flange 24 within which the paper washer is seated. Said flange is of a hei ht in excess of the thickness of, the was er for purposes which will appear later herein. Said flange is preferably beveled on the outside and said beveled wall is perforated at one point by passage 25 leading to channel 39 cut lengthwise in the interior Iwall of said plunger 8. Thispassage 25 and channe139 is rovided for the passage of the string upwar ly through plunger 8. Surrounding the upper end of plunger 8 and projecting la short distance thereabove is presser-sleeve 26 for coaction at predetermined times with presser-ring 5 on upper plunger 2. Said presser sleeve is mounted or free rotation on said plunger and may be supported on ball-bearing 2 to that end.

Between said ball-bearing and the lower end `of the sleeve is spring 28, wrapped about lunger 8 for urging said sleeve upwardly. he upward `movement of said sleeve is limu ited by pin 29 thereofin engagement with groove 30 around plunger 8.

yContiguous to plunger 8 and adjacent its upper end when that end is in its lowermost position of Fig. 5, is the string cutting mechanism. This mechanism comprises fixed blade 31 supported from bearlng, 16, and movable blade 32 pivoted at 33 to the fixed blade. Said movable blade may be oscillated relatively to fixed blade 31 at suitable times to lsever the strin therebetween by the following means: andle 34 is adjustably mounted in slide bar 35l and said slide bar is pivoted at that end thereof opposite handle 34, to one arm of bell-crank 36 pivoted at 37 in a fixed part of the framing. The other end of said bell-crank is pivoted to one end of link 38 the other end of which is pivoted to movable blade 32.

relation with plungers 2 and 8. For causing the reciprocation of said slide, bell-crank lever 45 is pivoted at 46 to a fixed part of the framing, one arm of saidV bell-crank being bifurcated for engagementjwith pin 47 fixed to said slide, and the other arm pivotally connected'to link 48, which is actuated at predetermined times by means not shown, for causing said'slide to reciprocate as described.

Similar stack 49,v washer slide 50 and bellcrank 51, are provided to sup ly a second washer below the plane of dehvery of said first `washer. supply devices are arranged in angular relation back of the transverse central plane 1, 1 of Fig. 2, and preferably midwayy -between them 1s located the eyelet supply.' -Said eyelet supply may comprise hopper 52 pivoted at 53 in bracket 54A outstanding from bearing 7 chute 55 whose delivery nose 56` is adapted to be oscillatedv about pivot 53, into and out'of engaging relation with plungers 2 and 8. Said'eyelet hopper and chute-may be oscillated the required distance and at predetermined timesby means of link 57 pivotally connected to arm 58 of said hopper. In many cases it is desirable to set la washer and eyelet on the body of the envelope alt the same time that the ilap equipment is being provided. To this end anvil arm 59 is provided outstanding from bearing 7 preferably directly opposite eyelet hopper 52. For coaction with anvil 60 on said arm, plunger For convenience these washer.

Depending from said 'hopper is eyelet 61 having spring supported needle 62 theref washer supdply 65 mayv also be provided,

actuated or adapted an and washers times.

It will be understood that, while plunger 2 is illustrated as reciprocating, such reciprocation, while desirable, is not essential to the successful operation of the mechanism. Die 4 thereof could very well be permanently located closer. to and just above the inner position of the leading end of washer slide 44. Or, if only one washer is applied (from slide 50), said die 4 could be permanently located even lower and closer to the position 'of the envelope flap 70, Fig. 1. In either of these arrangements plunger 8 would rise to meet said die.

AIt will also be understood that, while I have chosen to illustrate my improvements in connection with a washer .attached by means of an eyelet to asheet of material, my invention is equally eicient for winding a string about any member attached to a sheet of material and capable of retaining the supplying eyelets respectively at predetermined string thu.; wound.

For instance, said washer may be in the form of the common metal paper fastener having a head, round or of other shape, and two or more prongs bent over onto the opposite tace of the sheet ot' material and the string may be wound either about the head` or prongs. See Figs. 8 and 9.

The operation of my improved mechanism is as follows: Eyelet hoppers 52 and 68 being supplied with eyelets and washers 41 being stacked on their respectivel rods, as 42' of stack 41, an envelope is introduced to' the machine with its flap 70 in position over needle 21 and with its back port-ion 69 over anvil on arm 59, with the mechanism in osition just rior to that shown in Fig. 3.

he several e ements of the mechanism are then advanced to the positions shown in Figs. 1, 2 and 3, wherein the slides 44 and 50 have each delivered a washer into line with needle 21, and chute 55 has delivered an eyelet into similar relation. Also slide 71 has delivered a washer, and chute 72 has delivered an eyelet, into engaging position with needle 62. Also needle 21 has risen with sleeve 9 and passed through 'the' eye-.

let, the lower washer,'the envelope iap and .the upper washer, and is in engagement with die 4 in plunger 2. Also needle 62 has passed through the eyelet delivered by chute 72, the washer delivered by slide 71 and the back 69 of the envelope body. -The several l washer slides ande-yelet chutes then withdraw, as shown in Fig. 4, plunger 2 descends, sleeve 9 continues it upward movement, needle 21 bein forced downwardly in plunger 8 by anvi 4, andthe eyelet isA upset against said anvil, thereby securing the two washers on opposite sides respectively of the envelope Hap. At the same time plunger 61 descends and the eyelet is upset against anvil 60, thereby securing the v-washer to back portion 69.

The foregoing operations are all known in the art and are preparatory `to the following steps which embody the essential features of my improvements:I As plungers 2 and 8 meet for setting the eyelet on the envelope iap, presser-ringv '5 and presser- `sleeve 26 engage the envelope ilap on opstood that said string has previously lbeen led upwardly in channel 39 of' plunger 8 and out of the top of said plunger through angularly disposed passage 25, and that the free end of said string han over the outer edge of presser-ring 26. Said string 1s retained in position by spring 74.

The mechanism is now in position for winding the string between said ap and lower washer. This isv accomplished by liberating clutch latch 66 from engagement with lug 67 o'f gear 13, and which gear thereupon makes one complete revolution, when its lug 67 vis again engaged by latch 66, bringing that gear to rest.. This rota- 4-tion of gear 13 causes pinion 12 and plunger 8 Lto make two complete revolutions whereby string 73 isV wound twice about the eyelet as an axis, between the ila and the lower washer. The outer end of t e string being gripped between the 'anges respectively of ring 5 and sleeve 26, against the envelop flap, a lsui'licient portion of string y,tor winding between said washer and llap is drawn under tension of spring 74 from that port1on of the string within channel 39 of plunger 8.- Annular flange 24, on the upper endv of plunger 8, is eflicient to. cause the string, when being wound, to always pass above the washer, as the upper edge of that ange stands above the upper faceoi the washer. During the rotation of plungerv8,ring 26 will be held against rotation by its rictional engagement with lap which in turn is supported by ring 5. The rotation of plunger 8 will wind the string in cloclrwise direction and dispose it as A shown in Fig. 7. Plungers 2 and 8 then separate, the lower one retracting to the position of Fig. 5, adjacent the cutting mechanism. r] `he operator will then lift the Hap off needle 21 and move the envelope to the left, Fig. 3, thereby withdrawingl portion 69 from arm 59. String 73 will thereby be drawn be- 4tween blades 31 and 32.and presently the ing a portion of a washer to a sheet-of material, and means for winding. a string between the washer and the sheet of material.
